psrinfo Command
Option to Identify Chip Multithreading Features

Solaris 10: The psrinfo command
has been modified to provide information about physical processors, in addition
to information about virtual processors. This enhanced functionality has been
added to identify chip multithreading (CMT) features. The new -p option
reports the total number of physical processors that are in a system. Using
the psrinfo-pv command will list all the
physical processors that are in the system, as well as the virtual processors
that are associated with each physical processor. The default output of the psrinfo command continues to display the virtual processor information
for a system.
